We were test pilots of the program as they were still working out problems with the communicators. I noticed that the agent who approached us moved to different locations on different days. We were approached right before the Character Spot, but then I saw her a few days later over in the England pavillion.
As an adult - I was awed by the technology. Here is a snippet of why. One of the clues was to find something that lit on fire. We found a latern, lined the communicator up with it, took the photo and the latern ignited! It was so cool! (obviously it's sending a signal to the latern to start it - but even though I'm 37 - I still thought it was pretty darn cool!)
The other part that made it so magical was the agent that approached us! She talked to us very quietly almost whispering like we were going on a real mission and had to be quiet so no one would know we were spies.
I did a quick google search and found this info "Adventures will begin by acquiring a Mission Pass at Innoventions (East and West) or on the bridge between Future World and World Showcase. (That's the structure going up across from the Disney Vaction Club kiosk). That will send players to Team Possible Field Stations at Norway, Italy and the International Gateway."
If you'd like to find more info, the google search term that I used was "Disney's Kim Possible World Showcase Adventure" as I can't seem to post any links
